' HOOK BOLT.

Applicationfiletl January 26, 19 2. serial N'o. 531,844.

To all whom. it may concern.

Be it known that I, Lnwrs P. HALLADAY, a citizen ofthe United States, residing at Decatur, in the county of Macon and State of Illinois, have invented a certain new and useful Improvement in Hook Bolts, of

-which the following is a specification.

This invention relatesto a hook bolt,

adapted primarily for'use in connection with mounting bumper bars up'on frames of vehicles, and-particularly upon auto- The invention is illustrated more or less diagrammatically in the accompanying drawings, wherein:

, F'gure 1 is a si leelevation showing the bumper bar in position upon the frame of an automobile; p

Fig. 2 is a plan view of Figure 1;

Fig. 3 is a vertical cross section taken on the line 3 3 of Figure 1;

,Fig. 4 is a cross section taken on the line l l of Figure 3;

Fig. 5 is-an e'nd elevation of the wedge member ta'ken on'the line 55 of Figure 3.

Like parts are designated by like characters throughout. a

A indicates one of the channel section side frame members of an automobile chassis. These members are fastened together at one end between cross members B, adjacent which an upwardly extending lamp bracket.

B is mounted.

C is one of a. pair of bumper bar support ing'rods which carries atits forward end one end of the bumper'bar C, the details of which are not shown as they form no part of the present invention.

D is the hook bolt. It is composed of a hook shaped member as shown which has a straight shank and a curved end D, adapted to surround and overlie the lower flange of the channel section A, and to. be

- in contact withit only on its upper surface, 45.

and preferably only attwo points, -X and X, although it may be in contact'with it at other points on its upper surface.

Threaded upon the straight shank of the bolt D is the wedge member E which is adapted to lie between the lower flange of" the channel member A and the bolt','and

to contact the-lowerside of the'flange and to be wedged between the end curved portion D f the bolt and to contact the bolt with a wedge action at the point Y.

drawn and held in fixed The channel sections normally used in makin the frames-of automotive vehicles are formed so that the flanges of the sec-' tions are not parallel and are not at right angles to the side of the section, thus the upper and lower flanges of the channel section, as shown in Figure 3, are not at right angles to the vertical portion of the section.

In order toallow for this peculiarity in construction common to practically all automobile frames, and in order that the car.- rying bars C shall themselves be vertical,

the \wedge member E is provided with a vertical web E, which isnot at right angles to the prQ ecting member Thus when the wedge member E is'in, the position shown in Figure 3, the portion E is parallel to the lower flange of the channel secrtqon A, whereas the portion E" is parallel to thevertlcal portion of the section, and A 18 obviously itself vertical. The carrying bar C is threaded upon the straight shank D of the bolt, and the entire assembly is Figure 4, and thus a very positive grip isestablished.

. The use and operation of this invention are as follows:

This invention is designed-primarily for use where it is desirable to have an exceed ingly simple means of attachment. Thus" it is well adapted for use where no adjustment of the holding b ar upon the bolt is nece sary. It lS alsowell adapted for-use where the chassis is of unusual shape, or where the frame has mounted upon it projectin memberssuch, for example, as the lamp bracket here shown.

The bumper carrying bar is perforated in two places and is bent where necessary to avoid lamp brackets and other projections,

position by means and a single hookbo-lt is inserted in each A of 'the perforations. The inner ends of the hook bolt are hooked over the flange of the frame member and tightened. The

tightening. draws the bolt in upon the flange of the frame member and also forces the carrying bar were canted laterally, the

problem of attaching the bumper to the bumper carrying bar would be complicated and I have therefore provided a construction to avoid canting of the bumper carryin bar. I

hen the parts are as shown in Figures 1 and 2, the nuts are tightened and the hook bolts are drawn progressively upon the flange. If suflicient force is exerted the flange will actually be bent as shown in Figure 4.

I claim:

\ '1. A support for automobile bumper bars comprising a gripping member adapted parv tially to surround the flange of the automo-v bile frame member, a wedge element adapted to be inserted between said gripping.

member and, said flange and means for lon- 'gitudinally moving it to clamp said gripping member against said flange, the upper surface of said wedge element being axially hollowed to form substantially parallel flange engaging projections.

2. A support for automobile bumper bars comprising a gripping member adapted partially to surround the flange of the automo bile frame member, a wedge element adapt- It will be noticed that the ed to be inserted between said gripping member and said flange and means'for longltudinall moving it to clamp said gripping mem eragainst said flange,'the upper surface of said wedge element-being axially hollowed to form substantially parallel flange engaging projections,1 the opposed portion of the gripping member being adapted to lie along-and between said ,projecti-ons and in'opposition to said hollowed portion. 4

3. A support for automobile bumper bars comprising a gripping member adapted par-' tially to surround the flange of the automoj bile frame member, a wedge element adapted to be inserted between said gripping member and said flange and means for lon -gitudinall moving it to clamp said gripping mem er against said flange, said grip- .pi'ng element adapted to engage the flange at a plurality of separated points spaced along the len th of the upper-arm of the gripping mem er. I a

4. bumper bar support comprising a horizontally placed ban-adapted to be connected at its outer'end to abumper, and

adapted'at its inner end to be secured to a horizontal automobileframe member, the inner' end being perforatedat a plurality of points, a plurality of clamping members each adapted to be clamped upon the flange of said horizontal frame member, and each adapted at its outer end to penetrate and be secured'to the bumper support, the horizontal bar. comprising two horizontal sections connected by an upwardly inclined section, the upper most horizontal section be-- 'ing adapted to be engaged by the clamping members.
